Installation

Panel Cabling and Redundant Power

4-M/E Local Aux Panel

The Local Aux panel is typically powered through a cable connected to the
Main panel. If the Main panel has two power supplies, redundant power
protection for the Local Aux panel already exists. For additional redun-
dancy, an external power supply brick can be connected to the Redundant
DC Power In connector on the Local Aux panel. If desired, two separate
power supply bricks can be connected to the Main and Redundant DC
Power In connectors on the Local Aux panel.

2-M/E Panel

Local Aux control is integrated into the 2-M/E Main panel, but it has a sep-
arate processor. It is powered by a direct connection inside the panel. If the
2-M/E Main panel has two power supplies, redundant power protection
for the Local Aux panel already exists. You can optionally add an external
power supply that connects to the Aux Panel Redundant DC Power In con-
nector on the Main panel.

2-M/E System Cable Replacement

On older 2-M/E Kalypso systems a ribbon cable must be replaced with a
new cable supplied with the Emergency Bypass option. This cable routes
power from the Local Aux panel Backup Power option to the Remote Aux
subpanel. Newer 2-M/E systems are shipped with the correct cable already
installed. This ribbon cable is not used on 4-M/E systems.

Ribbon Cable Identification

1.

Open the 2-M/E Main panel lid.

If a ribbon cable connects three boards in the upper lid near the hinge
(

Figure 5

), it must be replaced to enable optional backup power with

the Emergency Bypass option. Go to

Local Aux Processor Interface Board

Version on page 14

.

If the ribbon cable connects two boards on the lid to the Local Aux Pro-
cessor Interface board, a new cable is already installed and does not
need to be replaced. Close the lid and go to

Control Cabling on page 17
